WILLIAM ANDREW ROBERT ANGUS, or mmm, mmrrona, cmm

To all whom it may concern:

Be it known that I, WILLIAM ANDREW Ronnnr ANGUS, a subject of Great Britain, and resident of the city of Winnipeg, in the. Province of Manitoba, Canada, have invented certain new and useful Improvements in Rail-Anchors, of which the following is the specification.

The invention relates to improvements in rail anchors and an object of the inventlon is to provide an anchor which will prevent a track rail from creeping on the t1es or the tie from'moving in respect to the rail.

A further object is to construct the anchor in a simple, durable and ine ipenslve manner and so that it can be readily put on and clamped in place. l

A further object is to provide the anchor with a clamping member that Wlll tighten in the creeping of the rail 1n say the pos1- tive direction, and will allow of movement of the rail in the negative direction under all conditions, and is further arranged so that it bites the rail at all times and a negative rail movement having occurred it relocks in the subsequent positive rail movement.

\Vith the above. more important ob ects n view the invention consists essentially 111 the arrangement and construction of parts hereinafter more particularly desor1bed and later pointed out in the appended clalms, reference being had to the accompanying drawing in which Figure 1 is a front view of the appllance as it appears attached to the rail base, the rail being shown in vertical sectlon.

Fig. 2 is a plan view of the parts'appearing in Fig. 1.

Fig. 3 is a horizontal sectional View at 3-3 Fig. 1 and looking downwardly.

Fig. 4 is a vertical sectional view at 4- 1 and looking to the left, the rail base being removed.

In the drawing like characters of reference indicate corresponding parts in the several figures.

1 is a track rail of ordinary construction presenting the head 2, web 3 and base 4. The rail is mounted on ties 5 in the usual manner, being fastened to the ties by spikes 6.

In actual practice it is found that the constant movement of traflic roduces a loosening of the spikes, a creeping of the rails on the ties and very often a movement of the tie in respect to the rail.

moves in the direction of the movement of .trafiic. In some cases however, such as in single tracking with trafiic in both directlons, the rail will cree in the direction of the heaviest traflio. ydevice, shortly described, is placed on the rails with due regard to the condition met with, its object being to prevent creeping in the direction which 1t occurs. The anchors used are constructed in detail as now described.

7 1s a shank'having one end fitted with a hook like stationary clamping jaw 8 and the other end presenting a horizontally disposed bearing face'9 with which I associate a vertically disposed neck 10 parallel to the railbase, a horizontally disposed inturned flange 11 extendino from the neck and overhanging the bearing face 9 and a vertical wall or web 12. This wall connects the flange, neck and base at what might be considered the rear side of the anchor and it is projected below the shank and is extended rearwardly to provide a vertically disposed bearing face 13 for engagement with the tie. By observing Fig. 2 it will be seen that this bearing face is contained in a vertical plane somewhat to the rear of the vertical plane containing the rear side of the shank so that when the anchor is in lace there is a clearance space 14 reserve between the shank, clamping jaw 8 and the tie.

The neck 10 and web 13 are continuous and are curved at their juncture point to provide a semi-circular bearing" face or shoulder 15 which forms the swiveling or turning point for a movable clamping member 16 shortly described in detail.

The shank 7 is somewhat longer than the,

width of the rail base on which it is used and it is here to be noticed that the left end of the shank is in a lower horizontal plane than the jaw end, this being accomplished by bending downwardly as indicated at 7 the body of the shank. This downward bend brings theunderside of the flange 11 into the same horizontal plane which con-, tains the underside of the base rail and provides also a wedge shaped clearance space indicated at 7 between the base of the rail and the bent part of the shank.

The clamping member 16 presents spaced upper and lower jaws 17 and 18 and an extending pivot arm 19, the jaws having their opposing faces shaped more or less complementary to the exposed faces of the rail base which the% grip, one on top and the other beneath. l

' pin is positioned preferably close to the rail base and somewhat'in the rear of the rear side of the clamping member 16.

When this anchor is to be used it is attached to the base of the rail and'adjoining a tie, due consideration being given to the direction in which the particular rail creeps. The direction of creeping of the rail in the present instance is indicated by the applied arrow in Fig. 2. The shank having been placed as shown with the stationary jaw 8 gripping one edge of the rail but clear of the face of the tieand the face 13 against the face of the tie at the other side of the rail the sectionman or such like person then inserts the clamping member 16 in the position shown with the jaws ripping the rail base and the arm seated in t e curved pocket 15. Although it is not essentially necessary to drive the clamping member in place it is as well to tap it with a hammer to insure of the initial comparatively tight gripping of the jaws 17 and 18 on the base of the rail.

After the member 16 has been put in place the pin 21 is inserted, this pin not I being used to maintain the clamping member tightly clamped in place but to limit the movement of the clamping member in the negative creeping movement of the rail.' The action of the anchor is as follows.

Upon the rail creeping in the direction of the applied arrow it carries the clamping jaw 8 with it as well as the jaws 17 and 18 which hang to the rail. The left hand end of the anchor cannot move by reason of the fact that the face 13 is engaged with the tie which is considered as stationary. I might also here explain that the clearance space 14 permits the jaw 8 to move toward the tie. The movement of the. parts above explained is comparatively small and momentary, for the instant this movement occurs the clamping member 16 swings in the direction of the movement of the rail and consequently causes the jaws 17 and 18 to move inwardly and grip the base of the rail more severely. The device is particularly quick acting as the double movement provided intensifies the quick gripping-feature. Ac-

ie arm 19 is adapted to pass between the flange 11 and face 9 and termicordingly any detrimental creeping movement of the rails is stopped.

When, under normal conditions, there is a negative or reverse creeping action of the rail, the whole anchor moves back with the rail, the clamping member remaining inert and tightly gripped. With abnormal conditions however, such as where frozen ground is met with and it is impossible for the shank to move in the negative direction, the clamping member can either swing back, or move bodily back with the rail, but in either case it maintains a gri on the rail base. goes bodily back wlth the rail, it engages the pm, such preventing it from getting out of proper alinement for return movement with the otherworking parts. The point which T wish toparticularly emphasize is that the aws of the clamping member never cease to grip the rail base sufiiciently tight so that 1t will not move back with the rail and relock it in all positive creeping movements.

-What I claim as my invention is 1. In a rail anchor, the combination with the base of a rail anda tie supporting the rail, of a member "adapted to extend under the rail at the side of the tie and having one end spaced from the tie and provided with means for engaging the rail base and the other end engaging the tie and provided with a bearing face extending beyond the rail base, a clamping member disposed on the said bearing face and at an angular position to the rail and having the outer end swivelly mounted and the inner find engaging the adjacent side of the rail ase.
